Experts predict that without change to current practises the global fashion industry could produce 2.5 gigatons of emissions by 2050.

Additionally, as the world's second-largest producer of industrial waste water discharge, the textile sector directly impacts millions of individuals worldwide. Alchemie Technology said this underscores the urgent need for sustainable practices and regulatory measures within the industry.

Alchemie said its low carbon Endeavour dyeing process delivers ‘significant sustainability benefits’ compared to traditional dyeing processes, which is in line with the company’s mission to eradicate pollution from textile dyeing and finishing processes.

The Endeavour technology facilitates the transition from wet dyeing to dry processing, and is said to reduce up to 85 per cent in carbon emissions and a decrease in waste water of up to 95 per cent.

Alchemie said that a traditional jet exhaust dyeing process uses large volumes of hot water, at temperatures of up to 135 degrees, for dyeing and washing, which requires large amounts of energy generated by burning fossil fuels to create steam.

The Endeavor waterless dyeing technology has a patented digitally controlled piezoelectric nozzle, which the company said can achieve 100-micro registration of 1.2 billion drops per linear metre of dyed fabric, ensuring the highest level of accuracy whilst reducing emissions.

The company said its digital dyeing process is also entirely end-to-end, from virgin fabric intake to fully fixed and softened fabric colouration output.

This technology is showcased in Alchemie’s first in-market production and demonstration facility in Taiwan, which focuses on polyester woven fabrics. The company said that the opening of this facility is a pivotal step in its 2024 roadmap, which includes the development of in-market production solutions for cotton woven and knits, as well as polyester with elastane.

In a statement, Dr Alan Hudd, founder and CEO of Alchemie Technology, said: “In light of the global fashion industry's staggering contribution of 2.1 billion metric tons of carbon emissions, equating to over three per cent of global emissions, there is an urgent need for action. As the world increasingly prioritises environmental conservation, energy efficiency and carbon reduction, there's a growing demand for low carbon dyeing technology.

“With the opening of our new production and demonstration hub in Taiwan, we are poised to forge partnerships with leading brands and textile players to unlock greater business opportunities and sustainability. These partnerships are not only about enhancing return on investment but also about driving tangible environmental benefits.”
